Abstract (en)
[origin: US2010295365A1] A master cylinder includes a first piston, a second piston, and a cylinder for housing the first piston and the second piston slidably in the axial direction. A first fluid pressure chamber, having a passage communicating with a reservoir tank, generates the fluid pressure when communication with the reservoir tank is interrupted at displacement of the first piston by a first stroke. Similarly, a second fluid pressure chamber, having a passage communicating with the reservoir tank, generates the fluid pressure when communi9cation with the reservoir tank is interrupted at displacement of the second piston by a second stroke which is smaller than the first stroke. A stroke simulator communicates with the fluid pressure chamber. A braking control apparatus is structured such that the second piston is first displaced when a brake pedal is pressed.
